go to "VERIFICATION OF VEHICLE REPAIR" procedure.

COMPONENT INSPECTION

1. Check battery

1. Connect scan tool to Data Link Connector (DLC).

2. Engine: ON

3. Operate headlamp, rear defogger, blower motor.

4. Measure voltage value of battery at 2000 RPM

Specification: 12.5-14.5V

5. Is the measured voltage within specifications?

YES

Go to step 2.

NO

Check connectors for looseness, poor connection, bending, corrosion, contamination, deterioration,
or damage. Repair or replace as necessary and then go to "VERIFICATION OF VEHICLE
REPAIR" procedure.

2. Check IPM

1. Connect scan tool to Data Link Connector (DLC).

2. Ignition "ON" & engine "OFF".

3. Substitute with a known-good IPM and Check if the DTC is erased.

4. Is the DTC erased?

YES

Substitute with a known-good IPM and check for proper operation.

If the problem is corrected, replace IPM and then go to "VERIFICATION OF VEHICLE
REPAIR" procedure.

NO

Check connectors for looseness, poor connection, bending, corrosion, contamination, deterioration,
or damage. Repair or replace as necessary and then go to "VERIFICATION OF VEHICLE
REPAIR" procedure.

After a repair, it is essential to verify that the fault has been corrected.

1. Connect scan tool and select "Diagnostic Trouble Codes (DTCs)" mode and then clear DTC.

2. Operate the vehicle and monitor the DTC on the scan tool.

3. Are any DTCs present?

YES

Go to the applicable troubleshooting procedure.

NO

System is performing to specification at this time.

GENERAL DESCRIPTION

To make system be more efficient, Body Control Module (hereinafter referred to BCM) applies CAN
(Controller Area Network) communication system. CAN is a kind of communication system which can make
related component share system information with just two line instead of complex individual signal line. It
consists of related component and CAN BUS which consists of CAN_high line and CAN_low line. Each
component can send and receive information by binary signal via CAN BUS. The related components for BCM
are IPM, ADM, DDM, FAM, RAM, IMS and cluster module, multifunction switch is sub-module of IPM. It
translates lamp, wiper, washer control signal from driver to IPM and according to this signal, IPM controls
units.
